An anonymous reader writes "Luther Martin of Voltage Security has published an article about the perception of cryptography today with regards to quality and honesty in vendors. From the article: 'Products that implement cryptography are probably credence goods. It requires expensive and uncommon skills to verify that data is really being protected by the use of cryptography, and most people cannot easily distinguish between very weak and very strong cryptography. Even after you use cryptography, you are never quite sure that it is protecting you like it is supposed to do.'"
